What You'll Receive
Full Description
Your business deserves AI that actually works in the real world — not a demo, not a prototype. This service delivers production-grade AI chatbots, intelligent agents, and custom large language model (LLM) applications, fully integrated into your existing web application and handed over with complete source code.
Whether you need a conversational support bot, a transactional AI assistant, a contextual knowledge-retrieval agent, or a full AI-powered website, this service is built around your specific requirements and business context.
**What You Get**
At every tier you receive direct integration of an AI model into your existing application, along with clean, well-structured source code you own outright. Upgrade tiers add AI model fine-tuning, full application and website design, chatbot integration as a standalone component, user authentication, and — at the highest tier — fully functional native iOS and Android apps. The scope scales clearly so you only pay for exactly what your project needs.
**How It Works**
Once your order is placed, you share your project details, any relevant credentials or access, and a brief on what you want the AI to do. The team reviews your requirements and begins development. Communication throughout the build happens via the order chat, so you are always informed. Revisions are included at every level so the final product reflects your vision precisely.
**What Can Be Built**
Conversational AI chatbots for support, sales, and transactional use cases; intelligent agents that automate workflows and user engagement; cloud-hosted or on-premise AI solutions; custom LLM applications using embeddings and vector databases for domain-specific knowledge retrieval; AI voice integration; and full AI SaaS platforms. Integrations span healthcare, finance, e-commerce, education, and beyond.
**Who This Is For**
This service suits product teams, startup founders, and business owners who want to add meaningful AI capabilities to an existing application or launch a new AI-powered product — without hiring a full in-house engineering team. It is equally suited to agencies seeking a reliable white-label AI development partner.
**Why Zinn Digital**
Based in London, England, with global delivery capability, Zinn Digital brings deep expertise in LLM development, embeddings, fine-tuning, multimodal AI, and scalable SaaS architecture. Both hosted commercial models and open-source LLMs are supported, deployable on your preferred infrastructure. Transparent communication and punctual delivery are core to every project — not an afterthought.

Frequently Asked Questions
You will need to share your project brief, details of the existing application or platform you want the AI integrated into, any relevant access credentials (such as API keys or repository access), and a clear description of what you want the AI to do. The more context you provide upfront, the smoother and faster the build will be.
Both are possible. The Basic tier focuses on integrating an AI model into an existing application. The Boost and Premium tiers include full application and website design, so a brand-new build is fully within scope at those levels.
The service supports both hosted commercial LLMs and open-source models. Fine-tuning, embedding pipelines, and vector database integration (such as Pinecone and Chroma) are available at Boost and Premium tier. If you have a specific model or infrastructure requirement, mention it in your project brief.
Yes. Full source code is included and handed over at every tier. You retain complete ownership of the code delivered.
Revisions are handled through the order chat. Once a build milestone or the final delivery is shared, you review it and submit your feedback. The agreed number of revision rounds is then used to refine the output until it meets your requirements.
Yes. The service supports both cloud-hosted deployments and on-premise installations depending on your infrastructure preferences. Please mention your preferred deployment environment in your project brief.
All communication takes place via the order chat on the platform. You will receive updates throughout the build and can ask questions or share additional context at any point. Transparent, timely communication is a core part of how this service operates.
Native iOS and Android application development is included exclusively in the Premium tier. The Basic and Boost tiers cover web application integration and, at Boost, full web design and chatbot components.

See what our customers say about this Zinn
Excellent ongoing work on the project, with all efforts contributing to its high quality and functionality.
We set up a multi-milestone project with Raheel and he did a great job on Milestone 1. We're excited to work with him on Milestone 2.
Second project with him now. I broke one large project into milestones and he's done phenomenal work on 2 of 6, proceeding to third after today. I'd highly recommend, I'll continue working with him for foreseeable future.
I've been a Zinn Hub user for over 10 years and this gig was definitely one of my favourites! The attention to detail, responsiveness and professionalism were outstanding! I would give one hundred stars if I could. Definitely looking forward to working with them again.
We worked with him to build a powerful CLI tool and upgrade our web IDE website, and the experience was absolutely outstanding. Their code expertise is exceptional. Everything they delivered was clean, efficient, and production-ready. The documentation was clear, thorough, and made implementation effortless. They are incredibly responsive and always available to answer questions or make quick adjustments. Collaboration was smooth and professional from start to finish. jhonnatrek678 went above and beyond to make sure everything worked perfectly. An A+ developer with excellent technical skills, communication, and reliability. We’re already planning to work with them again!
